Take the World Bank Carbon Fund as an example. The World Bank acts as an intermediary service (see figure 1). By virtue of its influence, the World Bank has attracted a considerable amount of funds and projects, and as the entrusting party, it has successfully docked buyers and sellers. This is a way to achieve emission reduction targets at a lower cost. Based on the scientific fact that greenhouse gases in the atmosphere are increasing, the gradual formation of the global carbon market makes it possible to achieve the same effect in reducing carbon emissions anywhere in the world. Therefore, through the operation of the International Carbon Fund, economic development and environmental protection as well as a win-win situation for developed and developing countries have been achieved.

In March 2007, China Clean Development Mechanism Fund (CDMF) was officially put into operation in order to actively promote the response to climate change and promote the sustainable development of China's social economy. The fund is stipulated in the Measures for the Management of Clean Development Mechanism Projects formulated by the Government of China, and consists of proceeds from clean development mechanism emission reduction projects, grants from international financial organizations, personal grants and other income approved by the State Council. The Fund is managed by the Clean Development Mechanism Fund Management Center located in the Ministry of Finance, and the Fund Audit Council composed of the National Development and Reform Commission, the Ministry of Finance, the Ministry of Science and Technology, the Ministry of Foreign Affairs and other ministries reviews the projects supported by the Fund to provide sustained and stable financial support for the country's climate change activities.
